Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a composition for colored flames, and the object thereof is to provide a composition for colored flames that can produce any color in flames and can sustain colored flames for a long time. The goal is to capture and provide information.

Generally, the flame formed by the combustion of fuel is blue-white or orange, which is a color similar to that of illumination light, so under strong illumination such as sunlight, it is necessary to visually check whether ignition has occurred. is difficult.

Conventionally, a gas lighter has been proposed that generates a colored flame, and in which a ring-shaped flame-colored body made of a metal, a metal compound, or a mixture thereof that exhibits a flame-color reaction is arranged in close proximity to the gas jet nozzle of the gas lighter. There is (Jikko 5th
1=Refer to Publication No. 53890).

However, since the ring-shaped colored flame body as described in 1-1 is solid, a colored flame is formed the moment the ejected gas is ignited, but the life of the colored flame is short and only temporary. That is, t f
Note f1J/In a flame-colored body formed in the shape of a ring, a substance that exhibits a flame-color reaction instantaneously evaporates on the surface of the ring-shaped solid that comes into contact with the flame, producing a colored flame, but immediately after it touches the flame. There is a drawback that the flame color body changes to a non-volatile oxide or carbonate, so the volatilization of the flame color body stops, and thereafter it no longer exhibits a colored flame.

As a result of intensive research to improve the above-mentioned drawbacks, the present inventors have found that by using a composition having the structure described in the claims, coloring that can easily and sustain a desired colored flame for a long time. I was able to get the flame. That is, the present invention uses methanol or a mixture thereof with ethanol t7c.
This is a colored Kakegawa composition characterized in that 5-16% by weight of a metal chloride, hydroxide, sulfate or an organometallic compound exhibiting a flame reaction is added and mixed.

The methanol used in the present invention is a first-grade reagent that is generally commercially available, and the present invention may use the methanol alone, or may be mixed with ethanol if necessary. Ethanol according to the Japanese Pharmacopoeia can be used for the drum, and if ethanol is mixed, it should be used at a ratio of 68% by volume or more of methanol and 32% by volume or less of ethanol.

In this case, if the mixing ratio of ethanol exceeds 32% by volume as described in II, the combustion flame of ethanol becomes too strong and the color of the flame compound becomes diluted, which is not preferable.

In addition, it is not preferable to use general solvents other than methanol or ethanol such as base/ethanol as the flame color compound because the color of the combustion flame of the solvent is noticeable. Therefore, in the present invention, methanol or methanol The flame color compound added to methanol or the mixture of methanol and ethanol generally contains various elements that can be detected by the flame color test.

Sr, K, Rb, Cs
+ In, Cu, Ca
+ Se + Ba+Co+Ni, Mn
chlorides, hydroxides or sulfates of elements such as, or organometallic compounds, and if necessary, two or more of the flame-colored compounds may be mixed as appropriate.

It is desirable that the various flame compounds can be dissolved in methanol alone or in a mixture of methanol and ethanol,
Therefore, if necessary, the flame-colored compound can be easily dissolved by treating it in advance with a trace amount of water or an organic substance such as acetylacetone or tetraphenylborate noda salt, and then adding and mixing it to methanol or a mixture of methanol and ethanol. be able to.

That is, some flame-colored compounds are difficult to dissolve directly in methanol or in a mixture of methanol and ethanol. In such a case, it can be dissolved by the treatment described above. For example, copper chloride can be easily dissolved in methanol due to the presence of trace amounts of water. In addition, when Li + +Rb etc., chloride or hydroxide etc. are reacted with sodium tetraphenylborate to produce lithium tetraphenylborate, potassium tetraphenylborate 1.
, Rubidium tetraphenylborate can be dissolved in methanol.

Furthermore, Co + Ni, Sr + Ca +
For Cu + Mn, etc., bisacetyl-1'-cobalt (I+), bisacetylaceto-1, etc., obtained by reacting chlorides and hydroxides of these metals with acetylaceto/ Diaco-strontium, bisace-f-eldoceI-sl = diaco-Φcal/um.

Bis-1'Sedyl-no-'Set-S1...Copper, Bisacetylace[-J-1, Nickel (11) or Bisacetylace[...S1...Man is 7th grade, complete. Can be dissolved in

However, in the present invention, it is not an essential condition that the flame compound is dissolved in methanol or a mixture of methanol and ethanol, and a suspension in which the flame compound is added in the form of fine powder may be used.

Furthermore, if too little of the flame color compound is added to methanol or a mixture of methanol and ethanol, the desired colored flame will be too diluted, and if it is too much, the flame color reaction will be hindered. Therefore, the flame color compound should be present in an amount of 5-16% by weight based on methanol or a mixture of methanol and ethanol.

In the present invention, when ignited, the flame-colored compound added to methanol or a mixture of methanol and ethanol is volatilized by the combustion flame of methanol, etc., and an arbitrary predetermined colored flame can be obtained. By mixing the different combustion flames, the separate combustion flames can be made into any desired colored flame. Moreover, in the present invention, since the flame color compound is uniformly mixed in methanol or a mixture of methanol and ethanol, the flame color compound can be continuously supplied to a separate combustion flame together with methanol or a mixture of methanol and ethanol. Therefore, it has the remarkable effect of being able to maintain the colored flame for a long time.

Therefore, in a combustion furnace or the like having a plurality of burners, the composition of the present invention, in which a different flame color compound is added and mixed, is supplied into the combustion flame of each burner, so that the combustion flame of each burner becomes a different colored flame. By observing the colored flame, abnormally burning burners can be easily detected.

If the present invention is housed in a container and the above-mentioned self-container is installed in a device or appliance to feed into the combustion flame of a combustion device or vessel J1, etc., it can be used for marine rescue. Easily send flares, signal bombs, etc. for communication between multiple fishing boats or ships scattered on the sea? JJ, and can facilitate the transmission of various types of information.

Furthermore, since the ordinary combustion flame of the conventional example can be easily changed to a colored flame having any desired color, the ignition flame can be maintained at all times during combustion when used in gas lighters, etc., and the design taste can be improved. If you encourage it, you will get angry.
